SPECIFICATION forming part of Letters Patent No. 300,316, dated June 10, 1884.

Application filed September 23, 1883. (No model.)

all GROUT/it may concern.-

Be ithnown that we, CHARLES S. FOWLER, of Brooklyn, in the county of Kings and State of New York, and Lucius A. RoonwnLL, of the city, county, and State of N cw York, have invented certain new and useful Improvements in Oraclccr-lllachines, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of rei'creneeindicate corresponding parts in all the figures.

Figure 1, Sheet 1, is ascctionalside elevation of ourimprovementshown as applied to a part of a cracker-machine. Fig. 2, Sheet 1, is aplan view of the improvement, partly in section. Fig. 3, Sheet 2, is a sectional end elevation of the machine, taken through the line mm, Fig. l.

The object of this invention is to promote convenience in adjusting cracker-machines.

The invention consists in the combination, with the gear-wheels connected with the feedrolls, and the gear -wheels connected with the driving gear-wheel, of a sliding shaft and a sliding plate provided with hearings for the gearavheel shaft-s, an adj llStlllg-SCFGW, a clam ping-screw, and a slotted supportingframe, whereby the said gearing can be readily ad justed for use with a larger or asmaller driving gear-wheel.

The lnvcntion also consists in the combina that it can be replaced by a larger or asmaller wheel, according as a faster or slower movement of the feed-rolls may be required. The teeth of the gear-wheel C mesh into the teeth of the gear-wheel D, attached to the shaft E, which revolves in bearings F, attached to or formed upon the plate G.

To the shaft E is also attached a beveled gear-wheel, H, the teeth of which mesh into the teeth of the beveled gear-wh eel I, attached to the lower end of the shaft J.

To the lower side of the plate G is attached a nut, K, which projects into the interior of the slotted bar orframe L, secured to the side of the frame A in such aposition as to be parallel with the shaft J.

M is a screw, which is swiveled to the upper end of the bar or frame L, and is threadedinto the nut K.

To the upper end of the screw Mis attached a hand-wheel, M, for convenience in operating it. The sliding plateGis secured in place, when adjusted, by a screw, N, formed upon the nut K, and which passes down through a slot in the frame L, and has a nut, N, screwed upon its lower end, so as to clamp the said nut K, and with it the plate G,'securely in place. Vith this construction, by turning the hand screw M, the plate G and its attachments will be moved toward or from the drive-shaft B, to adjust the gear-wheel D to mesh into a smaller or a larger gear-wheel, C, as may be required.

The lower part of the shaft J revolves in bearings 0, attached to the upper part of the plate G. The upper part of the shaft J passes through the hub of the beveled geanwheel P, and is connected with the said hub by a tongue and groove or other suitable means, so that the said shaft will carry the said gear-wheel with it in its revolution, and can slide freely through the said gear-wheel. The hub of the gear-wheel P revolves in hearings Q, attached to the frame A, and has an annular rib or flange formed upon it, which fits into an aunular groove in the bearings Q, so that the said hub will be held from longitudinal move ment, while being allowed to revolve freely. The teeth of the gear-wheel P mesh into the teeth of the beveled gear-wheel R, attached to journal of the lower feed-roll S. Thejournals of thelower feed-roll S revolve in hearings in standards T, attached to the frame A. The upper parts of the standards T are slotted vertically to receive the bearings U, in which revolve the journals of the upper roll S, which bearings are held down by screws V, passing through screw-holes in the caps \V, attached to the upper ends of the standards T, and having beveled gear-wheels X attached to their upper ends, to mesh into beveled gear-wheels Y, attached to the shaft Z. The shaft Z extends across the machine, and has a handwheel, a, attached to its ends, so that the rolls S can be readily adjusted at any desired distance apart. WVith this construction the gearwheels connecting the upper end of the shaft J with the rollsS will be unaffected by the adjustment of the gear-wheels connecting the lower end of the said shaft J with the'driving shaft B.

Upon the driving-shaft B are formed, or to it are attached, eccentrics I), the eccentricstraps c of which are attached to the lower ends of the rods d. The upper ends of the rods (2 are jointed to the screws 0, which screw up into the nuts f. The nuts f are made long, are placed in bearings in the ends of the cross head 9, and have flanges h at their upper and lower ends, to rest againstthe upper and lower sides of the cross-head g, to hold the said nuts from longitudinal movement, while allowing them to revolve freely.

To the upper ends of the nuts f are attached worm-wheels i, into which mesh the worms j, attached to the shaft k. The shaft 70 revolves in bearings in standards attached to the crosshead g, and has a hand-wheel, an, attached to its end, so that both the nuts f will be turned at the same time and through the same space. The cross-head g is placed in vertical slots in the standards Z, so that it can move up and down freely, but can have no lateral movement. The cross -head g is provided with a cutterholder, a, cutters 0, and a spring-held guard or stripper, 1), in the ordinary manner. With this construction the cutters can be readily and accurately adjusted as the thickness of the sheet of dough and the necessary pressure may require.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The drivingshaft B, provided with a de tach'able gear-wheel, the shaft S, and its gear, in combination with the shaft J, pinion P, mounted thereon by a feathered connection, the said shaft J being provided with gearing at its other end, connecting it with the gear on the driving-shaft, and a bearing for the shaft J and the said gearing adjustable longitudinally of the said shaft J, substantially as set forth.

2. In a cracker-machine, the combination,

with the gear-wheels P R, the feed-rolls, the gear-wheels D H I, and the driving gear-wheel O, of the sliding shaft J, the plate G, provided with bearings F F O the adjusting-screw M, the clamping-screw N, and the supportingframe L, substantially as herein shown and described, whereby the said gearing can be readily adjusted for use with a larger or a smaller driving gear-wheel, as set forth.

3. The combination of the cross -head 9, flanged nuts f h, and mechanism for simultaneously operating said nuts, with the screws 6, driving-shaft B, and their connecting devices, substantially as set forth.

4:. In a cracker-machine, the combination, with the screws e, jointed rods d, and eccentrics b, the worm-wheels z, worms j, and shaft 7c, and the cross-head g, of the long nuts f, having end flangesflt, substantially as herein shown and described, whereby the said cross-head can be readily and accurately adjusted, as set forth.
